The most important one of these is the efficient separation of amphoteric compounds having isoelectric points (pIs) outside the pH range of the ampholytes applied, but the resolution of the components can be increased by an adequate setup in the injection protocol. In this study, the effect of the pH of the anolyte and catholyte on the selectivity and speed of isoelectric focusing was investigated. Changes in the pH values significantly influenced the resolution and the length of the pH gradient, while changes in the charge-state of components were also observed. Three ampholyte solutions (from different suppliers) covering only 2 pH units were used for the analyses of substituted nitrophenol dyes in uncoated capillary. With appropriate setup the components, with pIs not covered by the ampholyte pH range, migrated in charged state outside the pH gradient. This phenomenon is preferable for coupling isoelectric focusing to mass spectrometry detection, by evading the undesirable ion suppression effect of ampholytes.

The separate injection of the sample and the ampholytes provides good condition to suppress and overcome the undesirable effect of the presence of ampholytes in mass spectrometry. By the appropriate selection of ampholyte solutions, whose pH range not necessarily covers the pI values of the analytes, the migration of the components can be controlled, and the impact of the ampholytes on mass spectrometric detection is decreased. The unique applicability of this setup is shown by testing several parameters, such as, the application of volatile electrolyte solutions, the type of the ampholytes, the order and the number of the ampholyte and sample zones. Broad and narrow pH range ampholytes were applied in experiments using uncoated capillaries with different length for the analyses of substituted nitrophenol dyes to achieve optimal conditions for the mass spectrometric detection. Although, the sample components are not leaving the pH gradient, due to the decrease in the ampholyte concentration at the position of the components, and because the sample components migrate in charged state, the ionization is more effective for mass spectrometry detection. Results with model calculations confirmed the mechanism of the process in the isoelectric focusing using one or two ampholyte zones before and/or after the sample zone.
